Today in my second ever BIOL111 Lecture (Cellular Biology and Biochemistry) we watched an animation from the Harvard Web called the inner life of cells. It can be found here. These things fascinated me, and thus I thought I’d share this here today.


“Microtubules are non-covalent cytoskeletal polymers found in all eukaryotic cells that are involved in mitosis, cell motility, intracellular transport, secretion, the maintenance of cell shape and cell polarization. They are polarized structures composed of alpha- and beta-tubulin heterodimer subunits assembled into linear protofilaments. A single microtubule is comprised of 10 to 15 protofilaments (usually 13 in mammalian cells) that associate laterally to form a 24 nm wide hollow cylinder.”
